PLOW.

SPECIFICATION forming part of Letters Patent No. 235,369, dated December 14, 1880. Application filed September 24, 1880. (No model.)

To all whom it may concern.-

Be it known that I, J OSEPH MASSON, of St. Louis, State of Missouri, have invented a new and useful Improvement in Plows, of which the following is a specification.

My invention relates to plows in which the angle made by the beam with the standard can be regulated by means of a screw connected with the beam.

Heretofore plow-beams have been rendered adjustable both vertically and horizontally by means of slotted plates with binding-screws, or by means of hand-screws connected with boxes and stationary nuts placed on the under side or in the rear of the heel of the beam; and the objects of my improvement are to locate the adjusting-screw used to elevate or depress the heel of the plow-beam within easy reach of the plowman while guiding the plow, so that he can regulate its action as circumstances and nature of the ground may demand in going forward or returning in. hillside plowing, without stopping the plow in so doing, and also to secure the adj usting-screw to the beam and handles in a simple but strong manner.

My invention consists in combining, with the slotted heel of the plow-beam, a top plate provided with a semi-spherical cavity in the under side thereof, a vertical brace connected with the landside plate or handle, and passin gthrough a slot in the beam, a screw-threaded horizontal brace, and a screw located above the beam, and provided with a crank-handle, for the purpose hereinafter described.

In the accompanying drawings, Figure 1- represents a perspective view of the plow Fig. 2, an enlarged view of the standard-hinge, and Fig.3 a vertical section of the beam-controlling parts of the plow.

In the accompanying drawings, A represents the beam,B the handles, G the standard, and D the landside-plate, of the plow.

To connect the standard with the beam the upper end of the former is provided with a slotted plate, 0, having two lugs, c, projecting above, and two lugs, 0 projecting under, be-

tween which lugs the standard passes, and is pivoted to the upper lugs at a The under side of the beam is recessed for the reception of the upper lugs, andthe plate 0 is secured to the beam with bolts (1.

To retain the beam at any desired angle with the standard there is secured to the landside handle of the plow (preferably between it and the landside-plate D at c) a vertical rod or flat bar, E, that is made to pass through a mortise cut in the rear portion of the beam. This bar is held at its upper end by means of a brace, F, having its foot f bolted to one of the plow-handles, and its head is made to rereceive the screw-threaded upper end of the vertical bar E, a nut, f, completing the union of the two.

The brace F has a boss, F, upon a portion of its length adjoining its head, that is bored through and screw-tapped to receive the screw G. This screw is secured,by means of a nut, g, to the under side of a plate, H, the latter being retained upon the top of the beam by bolts h.

The plate H is slotted centrally for the passage of the vertical rod E. The under side of said plate has a semi-spherical (or semi-cylindrical) cavity to receive a correspondinglyformed washer, h, placed upon the nut g, to allow the screw G to rock without loosening any of its bearing.

The cavity in the plate H may be made to receive a square bushing, and the latter be made with a semi-spherical cavity, as shown in Fig. 3.

The screw G has a handle, G, that projects above the plow-beam and brace F at a short distance in front, and in convenient reach of the plowman for him to rotate and regulate the working of the plow, although remaining at his post between the handles.

Having now fully described my invention, I claim- The combination of the slotted heel of a plow-beam, a top plate having a semi-spherical cavity in the under side thereof, a vertical brace connected with the landside-plate and passing through a slot in the beam, a screwthreaded horizontal brace, and a screw located above the beam and provided with a crank handle, substantially as and for the purpose described.

- JOSEPH MASSON.
